Welcome to summer

Summer rolled in this Tuesday morning, just after 1am. I wasn’t awake to see it, but I’m sure it was uneventful. Air stagnation is rearing its unhealthy head, mainly in the form of ozone. Ozone is formed by sunlight reacting with fluorocarbons, mainly exhaust from engines. It reaches its peak each day in the late afternoon and early evening, so those are the times to stay indoors if you’re prone to respiratory problems.

It looks like the fairly low humidity levels we’ve seen this week will continue until the end of the week. By Saturday, humidity will increase to the point where a few afternoon and early evening pop-up storms will be possible mainly east of I-35.
